The PSP model was selected for the SOI FET in the switch simulation for three reasons: 1) being a bodyreferenced model, PSP is more appropriate than a sourcereferenced model like BSIM for switch simulation purposes; 2) the bulk version of the PSP model enables simple integration of a userdefined substrate model; and. D 062019 C3M0065090D Silicon Carbide Power MOSFET C3M TM MOSFET Technology NChannel Enhancement Mode Features • C3M SiC MOSFET technology • High blocking voltage with low Onresistance. In practice a MOSFET is antiparallel with a diode. MOSFET: layout, crosssection, symbols • Inversion layer under gate (depending on gate voltage) • Heavily doped regions reach underneath gate ⇒. 1 EECS141EE141 EE141 Review What Have We Learnt?
